Specification of Letters Patent. Patented 0013.13, 1914.

Application filed November 14, 1913. Serial No. 800,946. i

To all whom it may concern:

Be it known that 1, JOHN KARTI-IEISER, a citizen of the United States,and a resident of the city of Aurora, county of Kane, and State ofIllinois, have invented certain new and useful Improvements inCar-Doors, of which the following is a specification.

My invention relates to car doors, and the object of this improvement isthe production of a simple and efiective car door which will close'thecar door opening of a car and be flush with the outside of the car whenclosed.

A further object is the provision of a hanger for the car door whichwill permit outward movement of the door in order to permit the door toslide longitudinally of the car and uncover the door opening.

A still further object is the provision'of smaller doors in the cardoor. Other objects will appear hereinafter.

With these objects in View, the invention consists in the combinationsand arrangements of parts hereinafter described and claimed. I

The invention will be best understood by reference to the accompanyingdrawings forming a part of this specification, and in which,

Figure 1 is a fragmentary elevation of a car equipped with myimprovement, Fig. 2

is a section of the same taken on line 2, 2 in Fig. 1, Fig. 3 is asimilar view taken on line 33 in Fig. 1, and Fig. 4 is a section takenat the same position as indicated in Fig. 3 but having the door movedoutwardly I ready to be moved to open position.

The preferred form of construction as illustrated in the drawings,comprises a car 5 having a door opening 6 and a door 7 fitted in thedoor opening with its outer side coplanar with the outside of the car.At the upper edge of door opening 6 is a track 8 substantially U-shapedin cross section, the lower edge of said track 8 being cut away topermit lateral movement of the door 7 in order to allow the door 7 to bemoved longitudinally of the car to open the same. On the inner side ofdoor 7 is secured a hanger 9. On the outer edge of the hanger 9 arejournaled rollers 10, the rollers 10 being adapted to ride on the lowerleg portion of the track 8. The rollers 10 are of such a width as topermit sliding endwise in order to permit the door 7 to be moved fromthe position indicated in Fig. 3, to the position indicated inFig. 4, inorder to clear the side of the car when moved on track 8. Rotatablymounted in bearings on the outside of door 7 is a rodl2vhaving atits'upper end a bent lever portion 13 engaging the blght portionof'track 8. At the lower end of rod 12 is a hand operablelever 14 bymeans of which-the rod 12 is rotated and lever member 13 engaged withthe outer edge of track 8 to move the door 7 from its position indicatedin Fig. 3, to that indi* cated in Fig. 4. In the upper portion of door 7is provided a small opening 15 and at the vertical edges of the opening,15 are guides 16. Mountedin the guides 16 for vertical movement is asliding door 17 held in closed position by means of a bar 18 and staple19 over which the perforated end of bar 18 rests. The bar 18 is lockedon staple 19 by means of a seal 20, or its equivalent. At the lower edgeof door 7 isvan opening 21 having'a door 22 hinged at the upper edgethereof, as at 23. "On the outer side of door 22 is a shaft 24 journaledin bearings 25 and provided at its ends with crank wheels 26. At thecente'r of shaft 24 is a lever 27 by means of which said shaft is lockthe lever in its upper position.

At the lower edge of'door'opening 21 are catches '32 and on door 22adjacent catches 32 are guides 33, and in the guides 33 are. slidablymounted locking bolts 34, the latter, being connected to the crankwheels by means of crank pins 35 so that in rocking the lever 27 toitslower position, the looking bolts 34 will be in engagement with catches32 to lock the door 22 in closed position, and upon rocking the lever 27to its upper position, the bolts 34 will be withdrawn from catches 32unlocking the door 22.

At one edge of door opening 6 is secured a plate 36 which overlaps door7 and serves as a lock therefor. 'At the other vertical edge of door 7are mounted two lockingbolts 37 which are pivoted to a lever 38 forsimultaneous operation. The locking ends of bolts 37 engage catches 39at the top and bottom of door 7 to lock said door in closed position.

At the lower edge of car 5 is a rod 420, and slidably mounted on the rod40 is the lower end of a chain 41, the upper end of chain 41 beingsecured to door 7 and adaptedto limit the outward movement of the bottom of door 7 during the longitudinal movement of said door in passingto its open position.

In operation the .door 7 is opened by manually moving lever 38 towithdraw bolts 37 from their catches. The lever 14 is then rocked tomove lever 18 which is in engagement with the outer edges of track 8 toswing the corresponding vertical edge of door 7 laterally of the car topermit longitudinal movement of said door to open the same. The car dooris then opened by manually moving the same longitudinally of the car.order to that just mentioned is enacted.

lVhile I have illustrated and described the preferred form ofconstruction for carrying my invention into effect, this is capable ofvariation and modification without departing from the spirit of theinvention. I, therefore, do not wish to be limited to the precisedetails of construction set forth, but desire to avail myself of suchvariations and modifications as come within the scope of the appendedclaims.

Having described my invention what I claim as new and desire to secureby Letters Patent is 1. In combination, a car having a door In closingthe door the reverse door, said hangers belng adapted to engage opening;a door in said door opening; a track substantially U-shaped in crosssection on said car; a rigid hanger secured on said door and having aportion extending between the legs of said U-shaped track, said hangerbeing adapted to move laterally of said track to permit movement of saiddoor laterally from said door opening; a rod rotatably mounted on saiddoor, having its upper end bent forming a lever engaging the bightportion of said track and a portion resting on the upper side of saidtrack preventing downward movement of the rod and its lower end bentforming an operatinglever, substantially as described.

2. In combination a car having a door opening; a door in said opening; atrack substantially U-shaped in cross section disposed with its bightportion directed away from said door opening and its upper leg securedto said car above said door opening; hangers secured to said door andextending into said track and adapted to permit longitudinal and lateralmovements of said the lower leg of said track and limit the outwardmovement of said door; and a lever mounted on said door, engaging thebight portion of said track and adapted to move said door laterally,substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

JOHN KARTHEISER.
